Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed September 18, 1914. Serial No. 862,294.

To all whom it may concern:

Be it known that I, FRED F. MAIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a .certain new and useful Improvement in Adding and Listing Machines, of which the following-is a specification.

The present invention relates to socalled tally-roll attachments for adding machines, and is an improvement upon the invention of my prior patent issued January 5, 1915, No. 1,123,337.

The principal object of the present invention is to make the tally-roll attachment in certain respects more automatic than the attachment of my prior invention, though that attachment is automatic in that it is moved into printing position by the regular paper carriage of the machine for the purpose of receiving an imprint of an amount when said paper carriage shifts to a certain predetermined columnar position, a duplicate imprint being made upon the paper overlying the roller platen of the carriage.

Certain classes of accounting work, in connection with which addin and listing machines are employed, call or the use of the tally-roll attachment to collect in condensed form totals of different groups of items, and one leading characteristic of my present invention consists in having the tally-roll attachment under the control of the adding machine devices which are set for the purpose of causing the ensuing operation of the machine to print a total.

In my prior construction, the tally-roll attachment included a spring for normally holding the tally-roll carriage out of printing position, and I there arranged for its being moved into printing position in opposition to that spring, so that it would automatically return to non-printing position with the back shift of the regular paper carriage from the particular columnar position where the tally-roll was needed, or otherwise through release of the tally-roll carriage. According to the present invention as here carried out, the arrangement is in a sense the reverse of that of my former application, in that a spring is applied to move the tally-roll carriage into printing position, such spring being normally restrained but adapted to be released by the setting of the totalizing devices. Thus, upon depression of total or sub-total key a latch is displaced so that the spring may operate to move the tally-roll carriage into printing posit-ion, though, according to the present embodiment of my invention, this does not occur until the machine proper is set in operatic-1P The arrangement is such that regular actuating elements of the machine proper serve to restore the tally-roll carriage to its original position in opposition to its spring, and the connections throughwhich this is done have to be released or relaxed before the said spring is able to move the.

tally-roll carriage into printing position. In addition to the above outlined control of thetally-roll attachment by the totalizing devices, I also arrange for its being brought into action at any time at the will of the operator. Thus the beforementioned latch, besides being displaceable by the said totalizing devices, may be displaced independently thereof. To this end I provide a special manipulative device which the operator can at any time use for the purpose of causing the tally-roll carriage to move to printing .position upon operation of the machine though such operation is not preceded by the setting of the totalizing, devices.

According to the present embodiment of my invention, the tally-roll carriage shifts crosswise the machine or laterally as does the regular paper carriage, the paper of the tally-roll moving in between the paper overlying the regular roller platen and the regular printing type of the machine. In order to prevent the tally-roll paper. from meeting any obstruction when moved in Or out through the somewhat restricted space between the roller platen and the type, I provide for rocking the roller platen as a preliminary to the shifting of the tallywroll paper into printing position, so that a wider space is opened up for the said tally-roll paper to pass through. Then the platen is rocked out of printing position before the tally-roll paper is shifted back to non-print ploy a paper guide and line finder which is substantially coextensive with the roller platen and adapted to bear against the same and follow it when rocked out of position to receive imprints,"said paper guide being formed to embrace the tally-roll strip so that when the roller platen is rocked back, said trip will be carried rearward and away from the type.

In the accompanying drawings, which form part of this specification and illustrate one form of embodiment of my present invention, Figure 1 represents in right side elevation a machine of the well known Burroughs type with the tally-roll attachment of my invention applied thereto and all the parts at normal; Fig. 2 is a left side elevation of said machine; Fig. 3 is a rear elevation of the same; Fig.. 4 is a plan view of the rear portion thereof; Fig. 5 is a horizontal section taken substantially on line 5- 5 of Fig. 3 showing the tally-roll carriage in printing position; Fig. 6 is a vertical section of the rear part of the machine with the tally-roll strip in printing positionand the roiler'platen rocked forward to receive the imprint.

Here, as in my former application, I have shown my invention as adapted to the well known Burroughs adding and listing machine which requires no detailed description in view of the numerous patents which have issued heretofore disclosing this machine and various improvements thereon, and also in view of the extent to which said machine has gone into commercial use. As to the machine proper, it is sufiicient to refer to the amount keys 291 which determine the extent of movement of the familiar levers 611 and therefore the setting up of the type carried by the familiar plates 618;

and to refer to the-familiar total and subtotal keys 265 and 265 which operate in the familiar way to cause the extent of movement of said levers 611 to be determined by backward turning of the addingpinions 916 to zero.

of items and totals is done in the usual way by driving the .type plates 618 rearward against a roller platen 13 carried in a cradle 14 which rocks in hearings on the laterally shiftable carriage 15 mounted across the back of the machine. Ordinarily the rocking of the platen into and out of position to receive the imprints from the type plates is done by hand'when adjusting paper or inspecting the work, and in some varieties of this machine as a preliminary to shifting the carriage. provision is made for automatically rocking the platen back and forthin order to better adapt the machine for use-with the tally-roll attachment, as hereinbefore mentioned. I find it convenient to accomplish The printing In the present instance rod 19 embraced by 'the jaws of said plate or bar and a rock shaft 20 mounted in the carriage 15. It will be understood that this rock shaft is oscillated in every operation of the machine. For the purposes of my invention 1 secure to said shaft a rearwardly projecting. arm 21 (Fig. 2) which at its rear end has a stud 21 occupying a short slot 22 in a link 22 whose lower end is connected by a spring 23 with said stud and whose upper end is jointed to an arm 2-1 secured .to the cradle 14. It will be seen that the arm 21 and link 21 will operate as a toggle whose partial straightening effects the forward rocking of the cradle and the platen, and the slot.22 provides for lost motion so that the platen may dwell in its printing position long enough to receive the imprint from the type, the spring 23 stretching as shown in Fig. 6. As in all of these Burroughs machines, the printing occurs at the end of the first'half cycle of operation of the machine, which in a hand-operated machine means at the end of the forward stroke of-the operating handle. The latter appears in Fig. land is designated 360, and there also appears in that figure one of the customary power springs 180 for completing the operation of the machine which, in the present instance, is accompanied by rearward rocking of the platen through the devices already described. Besides serving the usual function of giving the machine its first half cycle of operation, the handle 360 in the present instance is" utilized as a means for restoring the tally-roll carriage to non-printing position after it has shifted into printing position during the first half cycle of the machines operation. The details of connections through which this is V accomplished will be pointed out .after the tally-roll carriage itself has been described. The tally-roll carriage comprises a pair of horizontal rods 30 and 31, the former sliding in brackets 32 fastened to the upper rear portions of the panel frames of the machine casing, and the rod 31 sliding through brackets 33 secured to the base of the machine, and said two rods 30 and 31 being united by a 'certica-l rod 35 (Fig. 3) preferably made integral with the rods 30 and 31. There is secured to the upper rod 30 a paper roll holder, comprising side ars 36 and a connecting yoke 36, and also a cross rod 36 upon which the supply roll 37 is mounted. The said roll holder preferably extends forward over the top of the machine casing and the paper-37 from the roll passes down over said casing and between the roller platen and the back of the machine. and

thence down between the paper carriage track 15 and back of the machine. Though 1 carbonized paper may be used for the tally strip so as to provide for manifolding on the paper directly overlying the roller platen, I here show an ink ribbon 40 running from a supply roll 41 journaled on the upper carriage rod 30, said ribbon passing down just in rear of the strip 37 and between the latter and the? roller platen, and thence down between the carriage track 15 and the back of the machine.

.There is pivotally mounted in bearings 42 on the back panel 2 of'the machine (Fig. 6) a guide and line finder in the form of a metal plate 43extending across the back of the machine. This plate is not only arranged to rock in the aforesaid bearings but also to slide laterally therein, (being slotted at 43, as best shown in Fig. 3, where the strap-bearings 42 engage it) and it is formed .or equipped at the right hand end with a loop 44 (Fig. 4) which loosely embraces the upright rod 35 of the tally-roll carriage. The engagement of this loop with said rod causes the guide plate to move laterally with said carriage but permits the plate to rock back and forth without being obstructed by the carriage rod. A spring 45 connects the upper portion of said carriage rod with the forward portion of the loop so as to constantly tend to rock the plate rearwardly and keepit engaged with the roller platen. The plate is of sufiicient lateral extent to always overlie a considerable por'tion of the platen,-in fact it is preferably made of somewhat greater length than the platen. Consequently it is adapted to serve as an efiicien't guide and line finder for the paper overlying the platen while utilized, as will presently appear, for purposes of guiding and controlling the tallyroll strip and ink ribbon, for it can shift back and forth with the tally-roll carriage without overrunning the edges of the paper overlying the platen. For the purpose of subserving the function of guiding and controlling the tally-roll strip and ink ribbon, this plate, at about its middle portion, is formed at its upper edge with a loop or keemer 46 through which the tally strip and ink ribbon -pass.' This accomplishes a double purpose in that the tally strip and ribbon are kept in proper lateral position alining with the supply rolls and the ,takeup rolls presently to be pointed out, and in that both strip and ribbon will be held away from the back of the machine at the printing point when the lateral shift is effected.

It has already been pointed out how the roller platen is normally in a rearwardly rocked position and is rocked into printing position during the first half cycle of operation of the machine, and then rocked out again as the last half cycle of operation is executed, and it will be obvious from what has already been pointed out with respect to the guide plate, that this element follows the roller platen in its rocking movements and therefore, when the platen is rearward, as shown in Figs. 1 and 2, the tally strip and ribbon will be held back away from that portion of the back of the machine throughwhich the type operates. It will be understood that, as in all of these machines, there is an opening in the back panel of the casting just forward of which opening the type stands, and it will further be understood that the regular ink ribbon 49 of the machine (Fig. 6) passes down across this opening. The guide plate 43 is formed with two similar openings 47 and 48, one located where the tally strip and ribbon pass down in front of this plate and the other located to aline with the aforesaid opening in the back panel of the machine when the tally strip is out of printing position. It will be understood of course that the guide plate has two lateral positions one corresponding with the non-printing position of the tally strip and the other corresponding with the printing position thereof, and that in each position it is nec essary that the type shall be able to reach the roller platen or the paper overlying the same; hence the necessity for the two openings in said plate. It will be clear that the rocking in and out of the roller, accompanied by vibration of the guide plate and corresponding control of the tally strip and ribbon, will prevent interference between said strip or the ribbon and the regular ribbon of the machine or the type thereof, when the tally-roll carriage is being shifted laterally in and out of printing position. The tally strip and ink ribbon pass rearward through a slot 43 in the plate 43 and thence downward.

Referring next to the take-up rolls for the tally strip and ribbon, there is fastened to the lower carriage rod 31 a roll holder comprising side plates 50, -a journal supported thereby fora take-up roller 51, an also a journal rod 52 occupying short slots in the side plates 50 and connected by springs 53 therewith and supporting a pair of pressure rollers 54 bearing upon the take-up roller up roller 60 and a pawl 65 pivoted upon an arm 66 which journals upon the said rod 31 and is normally upheld by a spring 67 connecting it to the left side piece of the roll holder. Another spring 68 applied to the pawl holds the latter engaged with the ratchet wheel.

It is desirable to have the tally roll strip and its ribbon fed only when they are in v printing position in order that the selected imprints on the tallyroll strip may be in compact order. To this end I arrange, as in the construction of my prior application, to move the line spacing devices of the tally roll equipment into and out of operative relationship to the line spacing devices of the machine proper as the tally-roll carriage is shifted into and out of printing position. Thus the said pawl-carrying arm 66 carries a laterally projecting stud 66 which normally stands to the right out of line with the rear end of the line space lever 17 of the machine proper, as shown in Fig. 3. When the tally roll carriage is shifted to the left to bring the strip into printing position as shown in Fig. 5, the said stud is moved under said arm and the latter in rocking rocks the arm-to the position shown in Fig. 6, causing the pawl and ratchet to take eifect in advancing the tally roll strip and ribbon.

Referring next to the application of power to shift the tally-roll carriage, a spring 70 (Figs. 3 and 5) is attached at one end to the left-hand side piece 50 of the take-up roll holder and at the other end to the left hand bracket 33 so that said springtends to pull the tally-roll carriage to the left and bring it into printing position. The spring is normally restrained by a tape or band 71 which is coupled at one end to the right hand side of the said roll holder and at the other end to a downwardly extension 360 of the operating handle of the machine,-'said tape or band running over a sheave 73v in a bracket '74 secured to the foot at the right hand rear corner of the base of the machine.

purposes providing for some degree of ad- The plate at one end is here shown as engaged over a stud carried by the boss of the right hand side plate of the takeup roll holder, and the plate at the opposite end is here shown engaged over a screw stud fastened in the said downward extension'of the operating handle. The length of this tape or band is such as to provide for considerable slack when the handle of the machine is all the way forward (Fig. 5). Thus the printing position of the tally-roll carriage is determined by abutment of a collar 7 5 .on the lower rod 31 against the left hand bracketarm 33, and this comes about when the operating handle has been drawn forward only about one-third of its throw.

correspondingly, the retraction of the tally-v roll carriage to its non-printing position does not occur until the handle is executing the last part of its return movement. ThIS provides for the desired timing with respect to the rocking of the roller platen into and out of printing position. Thus the tally roll carriage shifts over to printing position at the beginning of the forward movement of the operating handle before the platen rocks into'printing position, and vice versa the platen rocksout of printing position before the back shift of the tally-roll car- Excessive movement of the latter to the right is prevented by abutment of a collar 75 on the rod 31 against the right-hand bracket arm 33.

Referring next to the matter of control of the tally-roll carriage by the total keys and special manipulative device heretofore mentioned, there is pivoted at thepoint 80 to theright hand framepiece of the machine proper a latch'in the form of a long bent arm 81 (Figs. 1 and 6) which at its upper ends extend in rear of the rod 30=and normally engages a notch 30 in the latter, thus holding the tally-roll carriage tothe right, as shown in Fig. 3. There is pivoted upon the right hand bracket 32 (Fig. 4) a finger piece 85 for displacing the, latch. This finger piece is pivoted to the bracket by a screw may be set tg put suflicient friction upon the piece to resist the tendency of the latch to return, or the handle of this finger piece may, through .ltS resiliency, serve such purpose in contacting with a portion of the bracket or with the head of one of its fastening screws. The finger piece is merely a flat piece of metal formed with a nose to engage the latch and with a handle extending conceniently for manipulation by the user of the machine. The acting end of the latch is preferably confined within a yoke-shaped portion of the said bracket, as clearly illustrated in Fig. 4. Obviously, this fin er piece enables the operator to unlatch t e tally-roll carriage at any time so that an imprint may be taken on the tallyroll strip of any amount set up on the keyclearly shown in Fig. l, and slottedat its out of juxta-relation to the printing mechforward end to embrace a stud 91 fastened in the arm 227 which vibrates with the total keys. This arm is a familiar element of a Burroughs adding machine, cured to a rock shaft 202 to which, at the left hand side of the machine, the total key lever 227 is secured. It will be understood also that depremion of the subtotal key 265 rocks the total key lever through familiar connections appearing in Fig. 2, and so the tally roll carriage is unlatched when the subtotal key is operated as well as when the total key is operated as well as when the total key is operated. A spring 95 connects the link 90 with said stud 91, as shown in' Fig. 1, said spring serving to engage the latch with the notch of the rod 30. The slot .in the link is for the purpose of permitting movement of the latch by the finger piece 85 without obstructionby the arm 227 or the necessity for pulling the total key down.
